Photonic-Assisted SBS Frequency & AoA Measurement | #WorldResearchAwards #Photonics
Introduction The advancement of modern radar and electronic warfare systems increasingly depends on the ability to detect, analyze, and interpret microwave signals with high precision. Traditional electronic measurement techniques face limitations in bandwidth, real-time performance, and interference tolerance, prompting the exploration of photonic-based solutions . The discussed research introduces a novel scheme utilizing stimulated Brillouin scattering (SBS) for simultaneous detection of frequency and angle-of-arrival (AOA) of microwave signals. By converting spatial information into optical domain interference and mapping spectral features through frequency-to-time transformation , the architecture achieves multidimensional parameter extraction in real time. This work highlights the significance of photonic sensing as a pathway to high-speed, wide-band, and highly accurate microwave measurement technologies.
